Nowadays, developers have a clear idea in choosing the configurations and code editors. Some of us spend endless hours on different extensions for configuring a code editor and switching back and forth within them. Irrespective of their volumes and functions, our ultimate goal is to create the best development environment, which is flexible and reliable to the user.

Without any doubt, Visual Studio is the most famous lightweight code editor experiencing severe competition from various code editors like Atom and Sublime Text and became prevalent because of its stability and performance. Along with these, it offers much-needed features like intelli-sense, available only in full-sized IDE like Visual Studio and Eclipse.

The VS Code receives the most favorable response from the marketplace. We should be thankful to the wonderful open source community, now the VS code editor ready for every framework, programming language, and development technology. It supports application libraries and frameworks in various ways, which mainly include Intellisense, syntax highlighting, snippets, and emmet features.

There are a considerable number of VS code extensions available these days for improved functioning.

In this article, I’m going to list out the top 10 VS Code Extensions for JavaScript to boost your productivity and better development experience.


Browser Extensions

While we are writing a console program in AngularJS using JavaScript, we execute script code within a browser. It means we frequently refresh the page to see the updates of code changes. Here are some tools available in the market, which significantly reduces the development time of an iteration process and avoids manual interaction.

Chrome Debugger: The best option to debug JavaScript is through chrome browser by placing breakpoints inside the editor.

Live Server: For static and dynamic pages, use a local development server with the feature of live reload.

PHP Server: For testing the javascript code at the client-end

Rest Client: It is a replacement for CURL program or browser to test the REST API endpoints. We can set up this tool to collaboratively run HTTP requests at right inside the editor.


Many developers are familiar with Prettier, and It doesn’t require much introduction. Before turned into the VS Code extension, Prettier is an opinionated code formatter. If we need code Prettier, we should install the convenient small extension[pun unintended].


ESLint is one of the most popular javascript linters, which later turns into the VS Code extension. Already if you are running ESLint in your project, you should add the extension for acquiring best results. By adding this extension, it does some extent of work for you.


In VS Code extensions GitLens is one of the most powerful and useful one, which provides features like code authorship, recent changes, blame, history and activity heatmaps etc. If you are looking to work on any repository with multiple contributors, then you should choose this.

Snippet Extension

While we are installing the snippet extension, it comes with many inbuilt snippets for Typescript and Javascript. This snippet will write the repetitive code very quickly, and if these inbuilt snippets are not sufficient so we can create one easily. Otherwise, we can add an extension which includes the bunch of helpful modern snippets.

Following are the most popular snippet extensions for the Javascript. We are adding these extensions for the sake of simplicity.

  • ES6 Snippet in StandardJS style
  • ES6 Snippet
  • JavaScript Snippet
  • Atom JavaScript Snippet


Quokka.js comes under the debugging category, and it is very suitable for Frameworks written with Typescript and Javascript. It executes the code very quickly as we type and exhibits many results in the code editor. Most developers are very familiar with Quokka.js for its prototyping, debugging and testing. But some developers feel that Quokka.js is not a perfect fit and have some distractions. Still, most of the developers prefer Quokka.js.

Fira Code

Fira code is one of the most popular programming fonts with the unique feature of ligature to scan the code very quickly. It takes several steps for setting up the editorial font, but it’s not difficult at all. Developers who want to make their code more accurate or look a bit bitter, then choose the comparison operators which worth it.

Babel JavaScript

Babel JavaScript application should be your priority while you are installing the VS code. It allows highlighting React, JSX and ES201x syntax, which most of the users feel flexible to work with. Most of the modern web applications may not look potential at the beginning, though does it make a difference in the long term.

One Dark Pro

One Dark Pro fetches Atom’s one dark iconic theme to VS Code. Most of the developers feel it is a less straining theme and more polite. It could be installed very soon when we transfer to the VS Code from Atoms. Though it is a personal preference, the VS Code has a fistful of decent themes you should try it.

Import Cost

Import Cost is one of the best extensions for the high size modules and packages to import into your app. This is the best way to provide the size of your application packages as small as possible!


Hence, VS Code is the best code editor with a vast number of extensions. It never is easy to write good JavaScript code but that can be overcome by the use of above-discussed extensions. These extensions are also handy if you prefer to write in TypeScript. The extensions such as ESLint, Fira Code are highly useful to avoid common mistakes, whereas the other extensions such as browser extensions help debug the code very quickly. For importing the modules, the Intellisense feature is beneficial. By using all of these tools, developers make the iteration process very quickly. I hope the above extensions could help you in your workflow and boost your productivity.
